1. WARNING
To prevent the risk of fire, smoke, orelectrical shock and toensure safe operation, please be
sure tofollowthe safetyguidelines below.
1. Atplaces where special caution isrequired, the necessarysafety
2

precautions are clearlylabeled or printed, for example, on the
cabinet, or on the part concerned. Please follow these safety
precautions, and also those listed inthe Owner'sManual.
2. Parts which have amark inthe circuitdiagram or inthe parts
list are essential for safety. When replacing these parts, be sure to
use onlythe specified parts.
3. Use the specified types for internal wiring (double-insulated
wiring, etc.).
4. When replacing parts on the AC primaryside (power transformer,
electricswitch, electrical cord, noise-prevention condenser, etc.),
wind the lead wire and secure itbysoldering.
5. Donot let the wiring come into contact with heat-emitting devices
(fuse resistor, radiator plate, etc.).
6. When replacing the wiring, make sure that itisnot incontact with
the unfinished or rough edge of apart.
7. When replacing the power cord (except for the plug-intype), tug it
from various directions to confirm that itdoes not slipout of
place.
8. Spacing
Ifsoldering was done on the AC primarycircuit, confirm that the
interval between the soldered terminalsor between the terminal
and surrounding metallicparts isat least the minimum required
(between the primarycircuitand the chassis: atleast 6.5mm;
between primarycircuitterminals: at least 4.0mm; between
primarycircuitterminalsand secondarycircuitterminals: at least
6.5mm.).
2. SAFETY PRECAUTION
2.1. Safetyprecaution
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use onlythe manufacturer’srecommended
components for safety.
3. Check the condition of the power cord. Replace ifwear or damage
3

isevident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to ashock hazard.
2.2. Insulation resistance test
1. Unplug the power cord and short the prongs of the plug with a
jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the
jumpered AC plug and each exposed metal cabinet part, such as
screw heads, connectors, control shafts, handlebrackets, etc.
Measurements shouldrange from 4MOhm to infinityfor
allexposed parts.
3. Handling Precautions For Traverse Deck
The laserdiode inthe traverse deck (optical pickup) maybreak downdue topotential difference
causedbystatic electricityof clothes orhumanbody.
So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pickup).
-Handling of traverse deck (optical pickup)
1. Donot subject the traverse deck (optical pickup) to static
electricityas itisextremelysensitive to electrical shock.
2. The short land between the No.4(LD)and No.5(GND)pins on the
flexibleboard (FFC)isshorted with asolder build-up to prevent
damage to the laser diode.To connect to the PCboard, be sure to
open byremoving the solder build-up, and finishthe work quickly.
3. Take care not to applyexcessive stress to the flexibleboard (FFC).
4. Donot turn the variableresistor (laser power adjustment). Ithas
4

alreadybeen adjusted.
-Grounding for electrostaticbreakdownprevention
1. Human bodygrounding
Use the anti-staticwrist strap to discharge the staticelectricity
from your body.
2. Work tablegrounding
Put aconductive material (sheet) or steel sheet on the area where
the traverse deck (optical pickup) isplaced, and ground the sheet.
Caution :
The staticelectricityof your clothes will not be grounded through
the wrist strap. So, take care not to let your clothes touch the
traverse deck (optical pickup).
Caution whenReplacing the Traverse Deck :
The traverse deck has ashort point shorted with solder to protect
the laer diode against electroststics breakdown. Besure to
remove the solder from the short point before making connections.

4. Precaution of Laser Diode
CAUTION:
This unit utilizes a class 1 laser.
Invisible laserradiation is emittedfromthe optical pickup lens.
Whenthe unit is turnedon:
1. Donot look directlyinto the pick up lens.
2. Donot use optical instruments to look at the pick up lens.
3. Donot adjust the preset variableresistor on the pickup lens.
4. Donot disassemblethe optical pick up unit.
5. Ifthe optical pick up isreplaced, use the manufacturer’sspecified
replacement pick up only.
6. Use of control or adjustments or performance of procedures other
than those specified hereinmayresultinhazardous radiation
exposure.
CAUTION!
THIS PRODUCTUTILIZES A LASER.
USE OFCONTROLS OR ADJUSTMENTS OR PERFORMANCE OFPROCEDURES OTHER THAN
THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
